Unable to build the docker image

General Discussions
1

I am following the tutorial mentioned in the official Docker docs to build a docker image .

I have cloned the repo,installed docker and followed all the instructions .
It then tells to run the following command : docker build -t getting-started .

My build starts but suddenly fails in step 4.Attaching the logs for your reference .

Hello,
its basically a network error in your Host machine.

you can check if DNS resolution is happening properly or not.

# for Linux check DNS
cat /etc/resolv.conf

if you are running docker behind VPN or proxy make sure it can access

registry.yarnpkg.com

below is output when I tried to reproduce

Great.Thanks for the solution.

I fixed it by changing my public DNS to point to Google’s DNS .
8.8.8.8 / 4.4.4.4 and now it works perfectly fine.
